Authorities hunt late-model Chrysler 300 with major front-end damage from driver slamming into a pedestrian in Mattapan

Investigators are looking for the driver of a dark blue or black Chrysler 300 that they've identified as the one that slammed into Pierre Desir on Morton Street early Saturday and then just kept driving early on May 26.

The car, which may have been brought in for repairs since then, likely has major front-end damage,possibly including windshield cracks, from where it hit and killed Desir, according to the Suffolk County District Attorney's office:

Auto body shops that may have worked on such a vehicle since May 26 are asked to contact investigators, as is anyone familiar with such a vehicle that was damaged or has been missing since last week. ...

Video footage from a camera at the intersection of Gallivan Boulevard and Dorchester Avenue shows the vehicle next to a larger SUV travelling westbound on Gallivan Boulevard, travelling from right to left and passing directly in front of the camera.
